1 chamber flowmaster

woodrow · August 15, 2003

i was looking at muffles and saw this 10 series 1 chamber delta

force race muffler, and was wondering if it will sound good on my

5.3 with the cats still on it. any info please.

depends on the sound you want

i know that 10 series would be VERY rumbly

but you already have the glass pack and duals anyway

so is that not loud enough for you or are you just going for a different sound

i just put on a magnaflow yesterday so really don't know how much i like it

yet but i did not want to go with the flows - i already had them before

Just take the muffler off completely. Flowmaster 40's sound the best I think. Im going with Borla though. Get rid of your cats too if you want. If you dont have really strict emmisions. The 5.3 and the LS1 makes more HP with no backpressure. My buddy has a 2003 Rado with 40 series Flows and a cut-out. He took off his cats too. When he has the truck on the rollers and the cut-out open he made 12 more HP than with it closed. Cranked out 322HP and 312rwtq(Has a cam, LS1Edit tuning and a few other things). I have heard a 5.3 with just the cats and no mufflers and it does sound pretty good!
